1. Uninstall bcrypt using `npm uninstall bcrypt` 2. Install bcryptjs using `npm i bcryptjs` 3. Update the references in the two files (`auth.js` and `users.js`) importing the “old” version from `const bcrypt = require("bcrypt");` to `const bcrypt = require("bcryptjs");` ---

Good morning, I am new to the forum and I am following the React tutorial where I had to setup that Vidly Node Backend and ran in the same kind of problems. I did lookup for solutions and eventually ended up on our usual StackOverflow. There I read about commands to type. Some did not seem to work. In the end I did install bcrypt 5.0.0 as one of the proposition told and it seems to have gone further. I can npm start. When I went to MongoDB Compass this morning I see a vidly DB. But there are messages in the npm start that make me wonder if there is something going wrong or would I maybe ignore thoses messages. Could anyone tell me ? I put the output bellow: ```auto PS D:\Partages\Scripts\web\reactProj\MH-React - Full\vidly-api-node> npm start > vidly@1.0.0 start D:\Partages\Scripts\web\reactProj\MH-React - Full\vidly-api-node > node index.js (node:13360) Warning: Accessing non-existent property 'padLevels' of module exports inside circular dependency (Use `node --trace-warnings ...` to show where the warning was created) (node:13360) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect. (node:13360) [MONGODB DRIVER] Warning: Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor. info: Listening on port 3900... (node:13360) DeprecationWarning: collection.ensureIndex is deprecated. Use createIndexes instead. info: Connected to mongodb://localhost/vidly... ``` Kind Regards. P.S. I add a screenshot of what I see in compass. ![image](https://us1.discourse-cdn.com/flex020/uploads/codewithmosh/original/2X/0/063d4cf54d12640f7b79fff695e32d9e52f7b20a.png) If there is a users “table”, shouldn’t I also see movies or other tables? If so, wouldn’t it indicate something did not go right? Further Edit: I started over and I am following instructions from the GitHub repo combined with what is here. So. Downloaded the files uninstalled bcrypt npm install bcrypt@lastest → which was 5.0.1 npm i → seems to have went fine node seed.js → seems to be OK npm test → many tests fail I installed jest-html-reporter to generate a test report. It doesn’t seem I am able to attach files here so I provide link. Expires in 7 days a.k.a. on 2021/06/30 [Test Report @WeTransfer](https://we.tl/t-dTNuZ3wJcO) Update: Some of the tests were failing because unlike what is in the course, there is a setting to disable authentication that is already disabled. Upon reenabling them, there are still failed test but way less. The link to report have been updated accordingly. ---
